Abstract [en]

We present a system allowing real-time image based lighting basedon HDR panoramic images [Debevec 1998]. The system performstime-consuming diffuse light calculations in a pre-processing step,which is key to attaining interactivity. The real-time subsystem processesan image based lighting model in software, which wouldbe simple to implement in hardware. Rendering is handled byOpenGL, but could be substituted for another graphics API, shouldthere be such a need. Applications for the technique presentedare discussed, and includes methods for realistic outdoor lighting.The system architecture is outlined, describing the algorithms used.Lastly, the ideas for future work that arose during the project arediscussed
